Summary: | A unit
1
for producing pyrogen controlled water on a small to medium factory scale comprises a number of charged ultrafiltration units
10
arranged in parallel. Orifice plates
15
are used to restrict and control the flow of deionized water to each filter
10
. The filter units
10
are mounted on a frame
2
with a wheeled chassis
3
which may be pushed or moved by a forklift truck to a site where pyrogen controlled water is required. The unit
1
has an inlet line
4
for connection to a supply of deionized water and an outlet line
6
for connection to a user of pyrogen controlled water. The unit
1
may be purged with nitrogen from a supply
18
. Sampling ports
17
in a common supply inlet
4
and a common outlet
6
ensure that the filtration efficiency can be closely monitored. The flow of water is monitored by a flowmeter
19
and pressure sensors
16
upstream of each filter facilitate a high level of control. |
